The Bose A30 Aviation battery-powered headset with dual plug, straight cable, and electric mic, is best utilized where noise is pervasive, comfort is required, and communication is critical. It’s the most comfortable, full-featured around-ear aviation headset Bose has ever created, and it’s the first-ever around-ear aviation headset with three modes of user selectable active noise cancellation. Each feature of the A30 was inspired by decades of Bose research and development and engineered to perform in high-intensity flight environments. Plus, its lightweight, comfortable design is FAA TSO and EASA E/TSO-C139a certified, proving its durability in tough conditions.
